The braided hose type flex pipe on my Hyundia would appear to be leaking. Not at the ends, but within the braid itself, indicating a hole or crack underneath I suppose. Is this a common prob with Hyundai?...I suspect that this might be the cause for my MIL to be on as well. When I scan the codes, it comes up with no faults.

Over time this flex pipe will leak which will cause an o2 sensor code.Replace the pipe clear the codes and monitor for any additional codes.
